Microsoft Announced Windows
On this day · 10 November 1983
Two years before a single copy shipped, Microsoft promised a graphical world running on top of plain old MS-DOS.
On November 10, 1983, Microsoft unveiled Windows, pitching it not as a standalone operating system but as a graphical layer that ran on top of MS-DOS. Bill Gates demonstrated the new environment to compete with rival graphical interfaces, most notably the one on the Apple Lisa.
The promise was a different way of working. Windows offered a window-management capability that let users view several unrelated programs on screen at once, plus pull-down menus, mouse support, and the ability to move data from one application into another. It was, in effect, a glimpse of how nearly every desktop computer would eventually behave.
Microsoft showed the future first and built it second.
The announcement ran far ahead of the product. Gates suggested the software would arrive within months, but development dragged on. Windows 1.0 did not actually ship until 1985, roughly two years after its debut, earning it an early reputation as long-delayed “vaporware” before it grew into the most widely used desktop platform on Earth.
